* U.S. CPI and Fed decision awaited * Bank of Thailand seen holding interest rate - Reuters poll * Indonesian stocks lowest since Nov. 2023 By Adwitiya Srivastava June 12 (Reuters) - Asian currencies held steady on Wednesday, while most equities notched modest gains ahead of a key U.S. inflation data as well as monetary policy decisions by the Federal Reserve and the Bank of Thailand. The South Korean won and the Malaysian ringgit inched up, while the Singaporean dollar, the Taiwanese dollar, and the Chinese yuan barely moved against the greenback. In Thailand, the baht and equities were steady ahead of the central bank's monetary policy decision in a few hours time. A poll of 27 economists by Reuters showed the Bank of Thailand (BoT) would leave its key interest rate unchanged. "The BoT will likely remain steadfastly on hold despite continued political pressure to cut rates," analysts at Barclays wrote in a note. "While there are media reports that the government may be trying to increase its influence on the bank through the post of the BoT board chair – which becomes vacant in September – we note that the chair does not sit on the monetary policy committee." Thai Prime Minister Srettha Thavisin on multiple occasions earlier has called for rate cuts, citing the need to boost Southeast Asia's second-largest economy, and is hoping for a rate cut later in the day. Meanwhile, investors widely expect the Fed to stand pat on its key interest rate later in the day. Market is now pricing in an around 52% chance of a rate cut in September, down from around 61% a month ago, according to CME FedWatch tool. Asian central banks have been on wait-and-see mode, as sticky inflation and tight labour market in the U.S. keep shifting expectations on when the Fed will cut rates and by how much. "Asia FX could face volatility from a potential upward shift in the Fed's median dot plot, which could push U.S. yields and the dollar higher," analysts at MUFG said. They added that low-yielding currencies such as the South Korean won, Thai baht, and Malaysian ringgit could be vulnerable. Elsewhere in Southeast Asia, stocks in Jakarta fell as much as 0.5% to hit their lowest level since mid-November, while rupiah ticked lower, flirting with a psychologically crucial level of 16,300 per dollar. Stocks in Kuala Lumpur were up 0.2%, while Taiwanese stocks ascended almost 0.8%. Financial markets in the Philippines were closed on Wednesday for the Independence Day holiday.
